Genes affected

HS3ST4 (HGNC:5200): (heparan sulfate-glucosamine 3-sulfotransferase 4) This gene encodes the enzyme heparan sulfate D-glucosaminyl 3-O-sulfotransferase 4. This enzyme generates 3-O-sulfated glucosaminyl residues in heparan sulfate. Cell surface heparan sulfate is used as a receptor by herpes simplex virus type 1 (HSV-1), and expression of this gene is thought to play a role in HSV-1 pathogenesis. [provided by RefSeq, Jul 2008]

The c.321C>A (p.S107R) alteration is located in exon 1 (coding exon 1) of the HS3ST4 gene. This alteration results from a C to A substitution at nucleotide position 321, causing the serine (S) at amino acid position 107 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
